IMPROVEMENT IN WATCH-WINDIN G- DEVICE.

To whom it'may conce/rn Beit known that I, ISAAC ICKELHEIMER, of New York, in the county and State oi' New York, have invented certain new and useful Improvements in IVinding Watches; and I hereby declare. the following to be a iiill, clear, and ,exactdescription of the same, reference being had to the accompanying drawings, in which- Figure` 1 is a perspective view of that part of a watch-movement. to which my invention relates.

Figure 2 is a longitudinal vertical section of the same.

Figures 3 and 4 are views of detached parts.

The mechanism in all the figures is represented on an enlarged scale, so as to illustrate more clearly the nature of the improvements. A

My invention relates :to that kind of winding-mechanism described in the patent of F. Robert Theurer, No. 52,505, dated February 6,1866, and assigned to Charles Rubens & Oo., of New York city, that is to say, mechanism whereby the winding may be eiiected by an oscillating, or back and forth movement of the key, and'which will admit ofthe key being turned `in the wrong direction without injury to the parts,

thus avoiding that risk which is incurred with ordi-y lnary winding-mechanism when the key is turned in the wrong direction, and also vavoiding the necessity of' removing the key from the winding-pin, or square, or of removing the hand from the key, as must be done when ordinary watches are wound up.

The object of my invention is to produce .an improved. and simplilied arrangement of parts.

To effect these results and to this end,

It consists in combining, in the manner hereinafter described,- With the ratchet-wheel of the spring-arbor and its retaining-pawl, a plate, carrying the springpawl, or click,A which moves the ratchet-wheel, and constituting' at the' same time the winding-stem, or square, to which the key is applied, so that when the plate, by means of its winding-stein, is oscillated in one direction, the click it' carries will ride over the mtcl1et-wheel, and when turned in theother direction the click will engage with and rotate the ratchetwheel; and my invention consists further in the combination with thejvinding-plate, whenthus combined and arranged with relation to the ratchet-wheel, of a cover or cap, fitting over and applied to. said plate, as hereinafter set forth. I

To enable those skilled in theart to make and use my invention, I will now proceed to describe the manner iu which the same is or may be carried into effect, by reference to the accompanying drawing.

a is the arbor oi' the spring-barrel, passing up through the bridge A, which is mounted in the watch in the usual manner, and carrying the ratchet-wheel b, by which it isl moved.

Upon thc ratchet-wheel is placed the circular plate, or disk c, which carries on its under side the click d and its springe, the same being arranged and applied, with relation to the ratchet-wheel, in the manner shown in figs. 3 and 4. A

The centre of the plate c is raised so as to form a. hollow winding-stem, or square f, which, when it is in position upon the ratchet-wheel, fits overthe upper end ot' the arbor a, the latter forming the axis upon which the plate, or disk revolves. t

The retaining spring-pawl, or c1ick`y'is secured to the bridge A, or in any other suitable position, so as to engage with the ratchet-wheel, as shown in igs. 1 and 4.

When the parts are thus arranged, it will be seen. that if the plate c be turned','by means of a key fitting upon the square f, in the one direction, the click d will engage with the ratchet-wheel, and thus cause the rotation .of the arbor a and the winding up ofthe spring,

the retaining-click g riding over the teeth of the wheel b.

When, on the contrary, the key is turned in the opposite direction, the spring-click d will rideover ,theteeth of the ratchet-wheel, which will, however, by

means of thel click g, which engages with it, be re--` tained in positionso that by the back-and-forth movementor oscillation of the key, and consequently of' the 'plate c, the winding can be eifected easily and expeditiously, and there can be no danger of injuring the parts by reversingthe movement of' the key.

In order to hold the winding-plate and parts con- -nected with itin place, andat the same time to admit of its free rotation, I place over thesame a cover, or

cap h, formed and secured to the bridge A, as represented in figs. -l and 2.

Its upper part constitutes-asocket, which protects the winding-square, while its lower portion is formed so as to iit over and hold in place, upon the spring-ar bor a, the winding-plate4 c, without interfering with the required movements of the'latter.

Having now described my invention, and the manner in which the same is or may be carried into effect,

What I claim, and desire to secure by Letters Patent, is

Y l. The combination, with the ratchet-wheel of the main-spring arbor and its retaining-pawl, of the winding-plate, with its vsquare stem and its spring-c1ick, for engaging withvthe said ratchet-wheel, all constructed and arranged for operation, substantially as herein shown and set forth. 1

2. The combination, with the parts named in the preceding clause, of the cover or cap, so constructed as to extend over and hold the winding-plate, and t0 constitute a socket for the vprotection of the windingsquare, as and for the purpose shown and set forth.

In testimony whereof, I have signed my name to this speciiication, before two subscribing witnesses.
